The antenna unit 20 according to the embodiment of the present application may be directly attached to the center frame 12 without being accommodated in the accommodating groove.

The radiator 21 is elongated, and the radiator 21 is disposed according to the structure of the second substrate 122. In some embodiments, the radiator 21 may include a first recess 25 and a second recess 26, the first recess 25 and the second recess 26 being located on the same side of the radiator 21, and a boss 27 being formed between the first recess 25 and the second recess 26. Wherein the length of the second recess 26 is greater than the length of the first recess 25, the second recess 26 being closer to the connector 22. When the antenna portion 20 is mounted to the middle frame 12, the first recess 25, the second recess 26, and the boss 27 are all distant from the first end 1211. Thus, the volume of the radiator 21 can be increased, and it should be noted that the structure of the radiator 21 according to the embodiment of the present application is not limited thereto. Such as: only the first recess 25 or only the second recess 26 or also the third recess and so on are provided.

In some embodiments, the connector 22 is located at the second via 1224 to make electrical connection with the printed circuit board 30.

In some embodiments, a step 23 is provided between the connector 22 and the radiator 21, and when the antenna portion 20 is received in the receiving groove 1221, the radiator 21 is higher than the connector 22. Referring to fig. 9 together, fig. 9 is a schematic structural diagram of a first screw according to an embodiment of the application. The nut 62 of the first screw 60 is disposed at the position of the connecting body 22 and is disposed at the same height as the step 23. Specifically, after the body 61 of the first screw 60 is screwed onto the middle frame 12, the nut 62 of the first screw 60, that is, the screwed position covers the position of the connecting body 22 and protrudes out of the connecting body 22, and is disposed at the same height as the step 23, so that the nut 62 of the first screw 60 and the radiator 21 are located on the same plane. It should be noted that, in the embodiment of the present application, the nut 62 may be disposed at a height lower than the step 23.

It should be noted that, in the embodiment of the present application, the radiator and the connector may be directly disposed on the same plane without providing a step, and specifically, referring to fig. 10, fig. 10 is a schematic diagram of another structure of the antenna portion provided in the embodiment of the present application, where the antenna portion 20a includes the radiator 21a, the connector 22a and the second through hole 24a. The antenna portion 20a is different from the antenna portion 20 in that: the antenna portion 20a is not provided with a step. The remaining structure of the antenna portion 20a can be referred to as the antenna portion 20, and will not be described herein.

In some embodiments, the printed circuit board 30 is provided with a fourth through hole 31, the printed circuit board 30 is disposed on one side of the middle frame 12, the antenna portion 20 is disposed on the other side of the middle frame 12, and the antenna portion 20 and the printed circuit board 30 are disposed on two opposite sides of the middle frame 12.

During the electrical connection process between the antenna portion 20 and the printed circuit board 30, the first screw 60 passes through the second through hole 1224, extends into the first through hole 1231, and is screwed with the first substrate 123. The second screw 80 passes through the fourth through hole 31, extends into the first through hole 1231, and is screwed with the first base plate 123. The first screw 60 and the second screw 80 each extend into the first through hole 1231 and are opposite. In some embodiments, the first screw 60 and the second screw 80 do not contact within the first through hole 1231, forming a space 1232 therebetween. Thus, the first screw 60 of the metal material realizes electrical connection of the antenna portion 20 and the first substrate 123 of the magnesium alloy material, and the second screw 80 of the metal material realizes electrical connection of the printed circuit board 80 and the first substrate 123. The antenna part 20 and the printed circuit board 30 are electrically connected by the first screw 60, the first substrate 123 and the second screw 80. The antenna is not only firmly fixed, but also has good electric connection effect and small interference to the antenna part 20.

In some embodiments, the diameter of the fourth through hole 31 is greater than the diameter of the first through hole 1231. Referring to fig. 11, fig. 11 is a schematic structural diagram of a second screw according to an embodiment of the application. The second screw includes a cap 83, a first body 81, and a second body 82, the second body 82 having a diameter greater than the diameter of the first body 81. Wherein the first body 81 is inserted into the first through hole 1231 and screwed with the first base plate 123. Wherein the second body 82 extends into the fourth through hole 31 and is screwed with the printed circuit board 30. Wherein the cap 83 of the second screw 80 mates with the surface of the printed circuit board 30.

As can be seen from the above, the first screw 60 and the second screw 80 can not only fix the antenna portion 20 and the printed circuit board 30, but also electrically connect the antenna portion 20 and the printed circuit board 30, which can save not only space but also the number of screws, or the structure and process for additionally fixing the antenna portion and the printed circuit board.

The first screw 60 and the second screw 80 are connected to the first substrate 123 together, so as to electrically connect the antenna portion 20 and the printed circuit board 30. The electrical connection of the antenna part 20 and the printed circuit board 30 by a first screw 60 will be described below.

In some embodiments, referring to fig. 12, fig. 12 is another cross-sectional view of an electronic device at an antenna portion according to an embodiment of the application. This fig. 12 is an improvement over fig. 7, and fig. 12 differs from fig. 7 in that: the antenna portion 20 and the printed circuit board 30 are electrically connected only by a first screw 60. Specifically, the first screw 60 passes through the third through hole 24, the second through hole 1224, the first through hole 1231, and extends into the fourth through hole 31 to be screwed with the printed circuit board 30.
